Abstract
An automatic speed reducing wheel includes a wheel unit and a speed reducing unit. The wheel unit includes a wheel seat, a wheel axle passing through the wheel seat, and a roller rotating about the wheel axle. A plurality of blockers is disposed on one side of the wheel frame in adjacent to an edge thereof in a radiation shape arrangement. The blockers rotate along with the roller. The speed reducing unit includes a fixing seat and a sliding member. The fixing seat is on one side of the roller and includes a sliding bore. The sliding member is slidably disposed in the sliding bore and includes an elastic portion having a blocking portion. When the roller moves downhill, the blocking portion of the sliding member protrudes out of an outer side of the sliding bore to interrupt a rotation route of the blockers, achieving a speed reducing effect.
